GRB 190829A - A Showcase of Binary Late Evolution

GRB 190829A is the fourth closest gamma-ray burst (GRB) to date (z=0.0785). Owing to its wide range of radio, optical, X-ray, and the very-high-energy (VHE) observations by H.E.S.S., it has become an essential new source examined by various models with complementary approaches.

In a new paper accepted for publication in ApJ, an international team (Yu Wang, J. A. Rueda, R. Ruffini, R. Moradi, Liang Li, Y. Aimuratov, F. Rastegarnia, S. Eslamzadeh, N. Sahakyan, Yunlong Zheng) studies the emissions from this celestial source and models the sequence of physical and related radiation processes in BdHNe and focus on individuating the binary properties that play the relevant roles.

NGC 362D: TWO RECORD-BREAKING FINDINGS SHED LIGHT ON THE EVOLUTION OF MILLISECOND PULSARS An INAF- and University of Bologna-led research team has discovered a binary system caught in an exceptionally rare evolutionary stage, consisting of a millisecond pulsar and the youngest white dwarf ever observed in a system of this kind

AN "IMPROBABLE" PLANETARY SYSTEM: COMPACT, COPLANAR, AND SHAPED BY A BROWN DWARF

Jun 17, 2026

AN "IMPROBABLE" PLANETARY SYSTEM: COMPACT, COPLANAR, AND SHAPED BY A BROWN DWARF An international team involving over ten institutions, with a strong participation from ESO and INAF, has characterised TOI-201 c, the transiting brown dwarf with the longest period for which mass has been measured. The study, published today in Nature, reveals a compact, coplanar system in which the presence of a massive, eccentric object redefines the stability boundaries for the inner planets

ALMA WITNESSES STAR BIRTH BEYOND THE EDGES OF THE MILKY WAY

Apr 22, 2026

ALMA WITNESSES STAR BIRTH BEYOND THE EDGES OF THE MILKY WAY A new study, led by INAF, has mapped, for the first time, the mass distribution of newly formed cores in the Large Magellanic Cloud. Thanks to high-resolution images from ALMA, it has emerged that these cores form according to the same patterns observed in the Milky Way. The result suggests that the initial fragmentation mechanisms of gas and dust clumps, from which stars are born, are universal and independent of the galactic environment.
